| ABSTRACT |
|
While perovskite solar cells (PSCs) have exhibited an impressive power conversion efficiency (PCE) of 26.1%, their inherent instability poses a significant obstacle to their widespread commercialisation. Researchers worldwide have diligently employed diverse strategies to enhance their stability, ranging from configuration modifications to employing varied manufacturing techniques. This review meticulously explores the latest advancements in PSC devices, focusing primarily on the strategies employed to fortify stability, with an emphasis on configuration structures and fabrication methods. The study explores the critical stability parameters and considerations relevant to the long-term stability of PSC configurations. A comprehensive examination of the evolution of PSC configurations is presented, encompassing transitions from regular to inverted designs, the introduction of hole transport layer-free designs, the incorporation of electron transport layer-free configurations, and variations in the use of organic and inorganic materials. Moreover, the review compiles pertinent articles for additional reference, providing a consolidated resource for researchers and enthusiasts in the field. This review offers recommendations to improve the stability of hybrid PSCs and provides a perspective on supporting the commercialisation of PSC technology. Addressing the stability challenges outlined in this review is crucial for unlocking the full potential of PSCs and facilitating their seamless integration into the mainstream renewable energy landscape. |
